Formed integrally with said arm inately itsmiddle portion in an arm 17, pro- 361s ahousing 38, which is adapted toreceive a post 39, upon which are pivotally mounted therecord-duplicating parts. The post 39 may be secured in any desiredposition by means of the set-screws 40. At its upper portion the post 39branches into forks41, between which is journaled a channel-piece 42,pro- Vided with a slot 43. Projecting rearwardly from the channel-piece42 is a threaded rod 44, upon. which is screwed a counterweight 45, saidcounterweight being designed to counterbalance the weight of thereproducing-stylus and appurtenant parts. An arm 46 is adapted to fit inthe channel-piece 42, being secured therein so as to have longitudinaladjustment by means of a set-screw 47, passing through the slot 43 inthe channel-piece. The arm46 is bifurcated at its outer end into arms48. Hinged between these arms 48 is the stylus-carrying arm 49, which isprovided with a stylus 50. A spring 51 is secured at one end to the arm49, and the other end is secured to a cord 52, fastened to a thumbscrew53 on. a post 54', the turning of the thumb-screw 53 adjusting thetension of the spring by winding or unwinding the cord 52. Upon eachside of the stylus-carrying arm 49 bears a leaf-spring 55, operating tomaintain the stylus-carrying arm 49 in alinement with the line runninglongitudinally through the center of the arm 46. Stretched between thearms 48 is a wire 56, which passes through an eye 57, formed in thestylus 50, and maintains the arm 49 in a plane substantially parallelwith the plane of the arm 46. Hinged on a cross-piece 58, extendingtransversely between the arms 48, is a supporting-piece 59 for therecord-cutting stylus 60, which is pivoted on a projection 61 on thesupportingpiece 59. The record-cutting stylus is secured to thetracing-stylus 50 by any desired means, as by a wire 62, passing throughthe aperture 63. The outer end of the supporting-piece 59 is providedwith a weight 64 and the opposite end with a tailpiece 65, whose limitof movement is defined by a set-screw 66. For the purpose of limitingthe oscillation of the channel-piece 42, upon which are supported thestylus-carrying parts, I provide a setscrew 67, passing through athreaded hole in a lug 68, projecting from the post 39.

An arm 69 carries a cone-bearing adapted to engage the shaft 26 and ishinged, so as to be capable of movement into and out of supportingposition for the purpose of removing the cylinder 25, and is locked inits closed position by means of a catch 70.

When a master-cylinder has been copied and its record duplicated on thecylinder 25, the operating-handle 15 is pressed down, thus turning thecam 10 and raising the masterrecord out of contact with therecord-tracing stylus 50. The cutting-stylus is then raised from contactwith the cylinder 25 by tilting the arm 36 by means of the rod 71lifting the same, the rod 71 extending under the end of the arm 36throughout the length of its path of movement longitudinally of thephonographcylinders. The rod 7]. and the rod 72, which are connected byend pieces 73, are secured to the plate 9 and are moved with said platewhen it is tilted by a cam 10. A limiting-stop 74 is secured on the rod71 and is adapted to be secured in any desired position by means of aset-screw 75.

What I claim as new is- 1. In an apparatus for duplicating soundrecords,the combination of two moving surfaces, one of which carries asound-record, means for duplicating the sound-record of one of saidmoving surfaces upon the other, and means for moving one of said movingsurfaces away from the sound-record-duplieating parts and moving thesound-record-duplicating parts out of contact with the other movingsurface, substantially as specified.

2. In an apparatus for duplicating soundrecords, the combination of apivotally-mounted record-cylinder, pivotally-mounted soundduplicatingparts, a second cylinder, and means for simultaneously moving therecordcylinder out of contact with the sound-duplicating parts and thesound-duplicating parts out of contact with the second cylinder,substantially as specified.

3. The combination of a rotatably-mounted cylinder, a pivoted supportfor one end of said cylinder, a link connected to said pivoted support,and a crank to which said link is secured, substantially as specified.

4. The combination of a rotatably-mounted cylinder, a pivoted supportfor one end of said cylinder, alink connected to said pivoted supportand provided with an arc-shaped portion, and a crank connected to saidarc-shaped portion, substantially as specified.

5. In an apparatus for duplicating soundrecords, the combination of twomoving surfaces, a sound-record-duplicating part, means for adjustingthe position of one of said moving surfaces relatively to thesound-recordduplicating part, and means for moving said record-surfaceaway from the sound-recordduplicating part and said part away from theother moving surface, substantially as specified.

6. In an apparatus for duplicating soundrecords, the combination of twomoving surfaces, an adjnstably-mounted sound-recordduplicating part,means for adjusting the position of one of said moving surfacesrelatively t0 the sound-record-duplicating part, and means for movingsaid record-surface away from the sound-record-duplicating part, andsaid part away from the other moving surface, substantially asspecified.

7. In an apparatus for duplicating soundrecords, a counterbalancedpivoted support, an arm carrying a tracing-stylus hinged to saidsupport, lateral guides for said arm, and means for holding thetracing-stylus arm in substantially the same horizontal plane as thepivoted support, substantially as specified.
